Unverified单火版智能开关依靠微弱电流维持自身供电，容易导致关灯后灯具微亮或频闪，尤其搭配LED节能灯（功率＜5W）时更明显。若不能改零线又要用LED，需加装'防频闪电容/镇流器'，或优选零火版94% similarUnverified单火线智能开关驱动LED灯时，若灯具功率＜3W（如小夜灯、单颗LED球泡）容易出现关不彻底的微亮或频闪，此时应选零火线方案或加装电容补偿模块92% similarUnverified接LED灯时若出现关灯后微亮/闪烁，是单火线感应开关取电导致，解决路径：优先换零火版→无法换线则并联电容(如1uF)或加装LED镇流器→仍不行改用带零线继电器款92% similarUnverified单火线智能开关工作时需从负载取电，接LED灯（功率＜5W）容易出现关灯后微亮、闪烁问题，此时应加装电容或改用零火版；零火版对负载类型无此限制92% similarUnverified单火线智能开关因需从灯具回路取电，容易导致关灯后LED灯微亮或频闪，若家中大量使用低功率LED灯，建议加装辅助电容或直接改零火线方案91% similar
